Steam Heat still making banging noises

Hi to all, and hope Mdshunk helps out as well. Well this steam heat has been a nigtmare, all piping on back of boiler has be done to specs from Burhman. Supply line 2inc, pitches away from boiler and down towards return line. All radiators and heat elements are pitch to return line, this is a one pipe system. If I drain the boiler completly out, she runs smoothly for ablout a day or two, then the banging and spitting water from the vents start. Can the boiler be bad?? Please guys help me out, I begun to hate steam heat, the heat is nice because its toasty warm, but the bangs are driving me nuts. Thanks to all. Happy New Year to all as well.

Hi helplesshandyman

You knew that I would be here, I thought you and Md had this worked out. It sounds like you are still ponding water somewhere in the system and the boiler fill system is doing its job. As far as mdshunk I would love to hear from him also. I have never seen such a sharp person give so much and put up with the stuff he has. I hope you can get him involved again. I think he would be proud of the member name I chose for myself.

Carrierman, I thought so too, she was running smoothly for two days after we repipe the back of the boiler. She has come back to hunt me. This has put a toll on me, it has slow down the construction in the house, but I need to get it to work. I have closed up all the walls, but cannot start installing wood floors until I get this straighten out. I do not want to ruin my new floors. This is my first home purchase, and its be a nightmare, I cannot afford to convert at this point. I hope Mdshunk gives me some ideas. I have noticed that the vent on the supply is not venting, so maybe the vent went bad with the water hammering. I am going to purchase another vent tomorrow and give it a shot. Thanks! Also forgot to mention, she never reached higher than 55 degrees. After repiping the back of the boiler, as per Mdshunk she reached 70 degrees and we had to shut her down because the house was so hot, new windows and new insulation throughout the house. I know that Mdshunk knows his stuff, I just hope he helps me out. Thanks!

Operating pressure is set to the lowest, I beleive its 0.5, the level is all the way down. I am going to change the vent on the supply line, but don't know if this will cause water hammering. Thanks for responding..

Previous owners stated boiler was working, the engineer checked it and found a gas leak on the gas control valve, so the gas was shut down by Fire Dept. The gas valve was repaired , and when we did the closing I never fired up the boiler since it was 85 degrees outside and we were getting ready for house demo, taught me a lesson tho! The boiler is not banging and runs quietly, its the radiators, once the water hammering starts, I hear it all over the house. Somehow the water is getting up to the radiators. If I drain the entire boiler out, she runs good for a day or two. Thanks for responding...

When its on its about 1/3, when its off its usually full to the top. Thanks again FYI all vents radiators and pipes are new. I had to change two vents so far, I think the water hammering mess them up, or these are cheap vents.

That's the one I am replacing, it was new when the new pipes were installed. To me it seems as its gone bad with the water hammering, because when the steam is going up, I stand near the vent and she is not venting, but I don't think this could be the problem, because this vent was installed new.
